DE2-115 Cyclone IV Board support in DSP Builder

I want to learn how to use DSP builder. But in the Simulink library browser listing of the supported boards, I can't see my board which is a DE2-115 Cyclone IV. I can't see any Cyclone IV based FPGA supported actually. Does anybody know if there are any plans to support Cyclone IV in the DSP Builder in the near future?
